Given numbers are 849, 729, 772, 645

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(849, 729) = 206307

GCD(849, 729) = ( 849 x 729 ) / 206307

= 849 / 729

= 849

Step2:

LCM(3, 772) = 2316

GCD(3, 772) = ( 3 x 772 ) / 2316

= 3 / 772

= 3

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 849, 729, 772, 645 is 1
